- IDEA 1 OF 8
Growth needs a disciplined method
Ellis and Brown describe growth hacking as a structured process of rapid experiments across a company.
Rather than relying on big marketing campaigns, teams test many small ideas and keep what works.
- IDEA 2 OF 8
Build a cross-functional team
The authors recommend growth teams that combine product, engineering, data and marketing skills.
When these functions work together, they can test ideas quickly without waiting for separate departments. Silos slow everything down for everyone involved.
- IDEA 3 OF 8
First, build a must-have product
Before pushing growth, the authors say, teams must check that customers truly need the product.
One test asks users how disappointed they would be if the product disappeared. Too few disappointed users signals a weak product.
- IDEA 4 OF 8
Choose one North Star metric
The authors suggest identifying a single metric that best captures the value customers get.
Focusing the whole team on this number aligns everyone's efforts toward meaningful growth. It keeps arguments about priorities much shorter.
- IDEA 5 OF 8
Test at high tempo
The book describes a cycle of analysing data, generating ideas, prioritising them and running tests quickly.
A faster pace of experiments produces more learning and more wins over time. Most tests fail, and that is expected.
- IDEA 6 OF 8
Activate users with an aha moment
The authors describe the moment when a new user first experiences the product's real value.
Helping users reach this aha moment quickly improves the chance they will keep using it.
- IDEA 7 OF 8
Retention beats acquisition
The authors argue that keeping customers is more important than attracting new ones.
Without retention, growth leaks away, so teams must work on habits, engagement and continued value. Leaky buckets cannot be filled for long.
- IDEA 8 OF 8
Monetise without hurting value
The book explains ways to increase revenue per customer, such as testing pricing and offers.
The authors warn that monetisation should not damage the experience that brought customers in. Trust is easy to lose and hard to regain.
